PRE-INSULATED PIPES FOR SOLAR INSTALLATIONS.
BiSolar offers a complete system of pre-insulated double pipes for solar installations.
STEEL PIPE
The base is made of a stainless steel corrugated pipe, made in
accordance with European standard 1.4404/AISI 316L from the
highest quality high-alloy steel with a very small amount of carbon,
plus chromium and nickel. This chemical composition guarantees
the low corrosivity, high durability and elasticity of the pipe.
AEROGEL BLANKET
The distinctive feature of BiSolar pipes is the use of high quality
insulation in the form of an aerogel mat, which has excellent
thermal insulation properties. The very low thermal conductivity
coefficient (λ=0.018W/mK) means that only a low insulation
thickness is needed – as little as 6.5 mm – to achieve the same
properties that competing products reach with a thickness
of 15 mm.
PVC COATING
Everything is protected by high quality PVC, which is resistant to the
effects of UV rays. The coating provides protection against external
factors, birds and rodents.
ELECTRICAL CABLE
The attached electrical cable connects to the temperature sensor.
The cable is covered in an additional silicone sleeve which is
resistant to high temperatures.
- HIGH ENERGY EFFICENCY
BiSolar pipes ensure a high level of solar
energy utilisation in solar installations,
guaranteeing the least possible heat
loss and the high efficiency of the solar
collectors thanks to the unique properties
of the aerogel insulation material. - LOW INSULATION THICKNESS
The aerogel mat is almost three times thinner than the material used in
conventional products, while maintaining insulation properties at the
same level. This allows the installation of BiSolar pipes in roofing, partition
structures and ventilation ducts. The use of thinner insulation also reduces the
space required for transportation and storage of the pipes. - HIGH DURABILITY
Using the highest quality materials in
BiSolar pipes means that the product
is exceptionally durable, its insulating
properties do not change over time,
and the additional layer of durable PVC
effectively protects against external
factors, rodents, birds and UV rays. - SIMPLIFIED INSTALLATION
The assembly of BiSolar pipes is not complicated.
The mounting flange of each pipe enables simple
installation on a minimum surface using ordinary
screws. No clamps are required.
Thanks to the reduced outer diameter of the pipes,
they can be mounted directly under roof tiles,
eliminating the need for expensive shaped tiles. - FIRE SAFETY
The materials used to produce BiSolar pipes have
a very high fire resistance class and are classified
as non-flammable or not easily flammable.
